What is artificial insemination at home? What are the differences between artificial insemination at home and artificial insemination in a fertility clinic?

As a result of a number of television programmes, as well as articles in newspapers and online, it has now become public knowledge that what we commonly know as artificial insemination at home is becoming an increasingly common practice.
The term could well be labelled incorrect or even deceptive if we take into account that insemination at home could never be on an equal footing to the artificial insemination carried out in a health clinic that has the necessary authorisation to carry out assisted reproduction techniques. The differences between the two are significant. […]

The role of seminal fluid in improving fertility treatment

There are two parts to semen: spermatozoa and the seminal fluid that the spermatozoa use as their means of travel.
Seminal fluid has traditionally been attributed the role of a simple means of transportation. However, many years ago, it started to become clear that exposure to seminal fluid with no spermatozoa content improved in vitro fertilisation results and the results in couples experiencing recurrent pregnancy loss.
Increased proof of this improvement in results has emerged over the last few months, as indicated in the recent scientific publications referenced at the end of this post. These pieces of scientific work confirm early observations and explain the reasons why. […]

Physiological conditions in embryo culture: reduction of the amount of oxygen in the incubator

Improving embryo culture by mimicking the conditions generated during in vivo culture is a key contributor towards improving success rates in couples who turn to in vitro fertilisation in order to solve their sterility issue.
In vitro culture of human embryos has traditionally been carried out in incubators in a controlled atmosphere at 6% CO2 and 21% O2. However, based on studies carried out on different species of mammals, we know that these conditions do not match those found in vivo in the fallopian tubes and the uterus where oxygen tension ranges between 2 and 8%. […]

What became of my embryos? Haven’t I got embryos to freeze?

These are just some of the questions that couples might ask at an important time during their treatment, just before embryo transfer.
In all cases of fertility treatment involving the in vitro fertilisation (IVF) laboratory, it is essential that all couples are given extensive, detailed and personalised information. This means talking about the embryo fertilisation and development processes.
When only a few fertilised oocytes are available as a result of poor ovarian reserve, transfer is carried out on day 2 or 3 of development in around 60% of cases because at this stage we can clearly select the embryos that are suitable for transfer. In around half of these cases it is not possible to cryopreserve embryos for future attempts. […]

A comparison of the phases in IVF and ICSI treatment

1.- Ovarian stimulation in the patient is carried out by administering doses of hormones that stimulate ovarian function with the aim of achieving sufficient oocytes. The doses of the aforementioned hormones are personalised to each patient depending on her ovarian reserve and based on the results of antimullerian hormone levels in a blood test and a follicle count for each ovary using a vaginal ultrasound scan. Controlling each patient’s ovarian response is done over a series of vaginal ultrasound scans (an average of 3) and, in some cases, by checking oestradiol (the hormone produced by the ovary) levels in blood. Once the checks indicate that the ovary is ready, oocyte retrieval is scheduled. This period of ovarian stimulation lasts between 8 and 10 days in most women and does not affect the patient’s daily routine. […]

Does being sexually aroused improve semen quality?

It has been scientifically proven that there are risk factors in our daily lives that have a negative impact on the quantity and quality of spermatozoa. These factors include emotional stress, doing a physically demanding job, sitting for prolonged periods of time, elevated local temperature, having high blood pressure and taking certain drugs over a prolonged period of time.
With this in mind, are there factors in our daily lives that are good for semen quality? […]

What are an embryo’s nutritional requirements prior to transfer to the mother?

During in vitro fertilisation processes, for the first few days of their lives, human embryos have to develop outside the mother’s body in special incubators.  Temperature and pH conditions need to be optimum and embryos also need to have access to all the necessary ingredients in order to feed and, in doing so, meet their energy requirements. Culture media are used for this. […]

What is a residual follicle? Diagnosis and treatment of a residual cyst

Residual follicle is the term given to the structure remaining in the ovary following a process of stimulation, whether this has been for insemination or during a cycle of in vitro fertilisation (IVF). Diagnosis is generally carried out using ultrasound imaging.
On the whole, before embarking on a course of ovarian stimulation, a basal ultrasound scan is carried out. The aim is to check that the ovary is resting. In other words, that it has antral follicles measuring under 10 millimetres in length. […]

How might salpingitis or inflammation of the fallopian tubes affect my fertility?

In order for natural conception to take place, three basic factors need to be come together: ovulation needs to take place, there needs to be an appropriate quantity of spermatozoa with appropriate mobility in the ejaculate and, in third place, the uterine tubes need to be permeable. The latter is essential in order for both gametes to join together (egg and sperm) and for fertilisation to then take place. […]

A less invasive, simpler technique: SOFT IVF or MINI IVF

Having a sufficient number of mature egg cells is one of the key steps to obtaining excellent results in a cycle of in vitro fertilisation (IVF). In order to achieve this, the ovaries need to be stimulated and, contrary to what happens during a natural cycle, the ovaries need to simultaneously mature an appropriate number of eggs.
The most commonly used stimulation protocols are based on the use of doses of follicle-stimulating hormone (FSH). These may or may not be administered along with other drugs and vary between 150 and 300 IU/day. The response will be somewhere between 7 and 15 follicles. […]
